38 hwy miles per gallon, lol, you kiddin me?

[pennystocks]

Did a small test run w/ my scan gauge on my way home from work.

Also note the 38 mpg on the window sticker, they dont go faster than like 63 mph.

46.8 - Avg miles per gallon (@ 55 MPH w/ cruise control was steady 45-48 MPG)
9.2 - miles drove
3004 - RPM max
55 - MPH max
37 MPH average (real average was 40-55 not counting stop lights)

Thats w/ like 3 full stop/starts at lights, and about 6 or so slow downs to like 20 mph (turns and wat not)

Did this one when i first got it today, just a quick test:

3.3 Mile drive
2228 Max RPM - Was Grandma'in it
37 MPH Max
24 MPH Avg - Was really 33 ish w/ the cruse on, but got caught a light, and amazingly enough, got caught at a turtle crossing the street LMAO
0.1 Gal. Fuel Used
190 Degrees F Max
53.1 MPG AVG oh yea, i love it


Thats just sick, i mean i hear of hybrids gettin alot worse milage than they say. I did a couple of tests while working, i could hold about 38-40 MPG pure city driving, i mean, i was drivin like a b*tch but still, i still cant get over it.

Latest one, all highway, no slow downs at all except one toll booth:

30.9 miles drove
3400 max RPM
61 MPH avg
51.2 MPG avg

[foober]

I'm getting around 40 miles to the gallon not driving like an old lady as welll. Its almost hard to believe. The yaris actually gets better gas milage than they had on the gas milage sticker. Probably the first time thats every happened. I wonder if the toyota people did that much research on the gas milage. Hard to complain.:thumbup:

[vicpai]

......however, could you guys specify whether your car is an automatic or manual??
Thanks!
Vic

[pennystocks]

Auto, the manual will probaly be 3 mpg more hopfully, but 6-8 weeks wait and driving 500 miles a week droped the idea for me, ahh it woudl have been fun tho :)

[NickNickNick]

It honestly is amazing...

I have been getting over 50mpg on the highway quite consistently, and well over 40mpg in the city...standard 5speed 3door, no babying.

I love it.

35$ for gas at 109 cents a L every 3 weeks.

[fearturtle44]

Hey, you have to drive more than a few miles to determine MPG. In fact, you probably average the MPG after 4-5 complete fillups. That way you have well over 1200-1500 miles for sampling mpg.

Kevin

[Idjiit]

It will interesting to see if your scangauge's reported MPG matches what you calculate for each tank through more traditional methods. Right now you're assuming the scangauge is correct, but that may not end up being the case.

And as far as hybrids not getting their estimated mileage - our Prius regularly gets 52MPG on the highway, which is precisely what the EPA estimates. In short jaunts around town it can get much higher than that.

[stuffy]

i can't believe the reports of 50 mpg, just can't. there can't be such huge discrepencies from car to car, unless there is a big difference in quality of the fuel that people are using.

the best i have ever achieved, averaged over 4 tanks, is 40 mpg (u.s.), 50/50 highway/city, driving like gramma, my car currently has 7400 km (4600 miles)

of course i've only ever used 87 octane, and according to the reading i have done, the higher octane fuel might only give you marginally better fuel economy.

[fearturtle44]

If anybody is getting 50mpg or above in their Yaris, then they are not doing the computation correctly. Nice to believe it but no way.

Kevin

[stuffy]

i wonder if some are doing a conversion from L p/100km to IMPERIAL galons as opposed to u.s. galons, i'm not sure what the difference would be, but here is a site that has been posted before:

http://www.sciencemadesimple.net/fuel_economy.php

[why?]

The difference is around 9 MPG. As in Imperial gallons are 9 mpg higher than US gallons.

And gas mileage is all about how you drive the car.

[pennystocks]

Well the 53 mpg was just a 30 mph cruise. And i'm pretty sure its accurate, 45-48 mpg sounds about right for 55 mph from what i'v heard.

And i know 9 miles of driving doesnt show much compared to like a 5 tank average, its just the fact that the car can get that good of mileage.

[stuffy]

pennystocks, what is it telling you when you drive it enthusiastically?

[ricko]

I'm getting anywhere from 37 to 39 miles/U.S. gallon in my 5-speed RS. Almost all of my driving is around the small resort town I live in, with only moderate traffic. I do some driving on open country roads, but so far NO highway driving at all. Results are based on 6 tanks since new, and were converted from L/100km using the above-mentioned converter. Please note I do tend to toss the Yaris around in an aggressive manner (certainly NOT in a fuel efficient way) and do enounter a lot of hills. As "Why" says, it is all about HOW you drive the car, and I am sure I could get much better results if that was my intention.

[Uglyboyed]

well im doin about 38-40 mpg and i drive on both the city and highway equally. but im a fast driver, i go between 80-90mph on the highway. Depending on the times i may go about 75mph but thats slooooow.

[JaiTomato]

Ok. My yaris is a sedan automatic with A/C. My weekly drive is also a 500 mile routine, 80% hwy / 20% city. I now filled up with my fourth tank of gas (avg $2.89/gal Yuck) I went from a high of 46mpg on the first tank (I was really driving like an old lady, not going over 60 or 65mph and didn't have to use the A/C. It then went lower to 44mpg on the second fill-up. On the last two fill-ups it started to settle at around 42.5mpg while no no longer driving like an old lady. I also added extra weight (subwoofer box in trunk). I'll be satisfied if this holds.

[foober]

Someone should do a 1,000 mile trip all highway not pushing it too hard to see what it gets in gas milage. Though it would be hard not to go 75 and 80 on a long highway trip. I believe one guy did that a month or two ago and got 45+ miles to the gallon. He might of reported better than that. But he was pretty amazed at its good long distance gas milage via highway miles.

I'd do it. But I've got to work now. But come oct. I'll be doing the trip thing.

[NickNickNick]

I'll be taking a 4000km "cruise" down Kansas within a month. We'll see how that goes.

[Dweeb]

Ya, I find getting more than 45MPG a bit unrealistic also.
I get an average of about 35MPG ( and I kind of baby it to see what is the best I can get)

Last fill-up 50%city , 50%hwy
40Liters / 10.57 Gallons and driven 575km / 357 miles.
That averages to 6.96L/100km or 33.81MPG.

I drive a 07 Yaris RS hatch, 5 speed, 5 door.

[pennystocks]

Yea, so far my average is about 33 mpg, but time is money and the 4 or 5 mpg isn't worth the loss on time, most of the time that is.

Seriuosly tho, crusing at about 50-55 will get 45+ mpg w/ no stops.

Just for you guys tho, i'll do a expressway run to my buddys house @ 55mph. The longest with no stops is about 15 miles long so that should give a nice average.

[YotaYarisUSA]

How many gallons does that Yaris use per fuel bar? I have 132 miles on my Yaris and the fuel bar went down once and I filled it back up to and that only took a little over two gallons I think? So far I'm really amazed at the fuel,I'm used to a V6 Ford Ranger 4X4 that got about 16 to 18 mpg.


YotaYarisUSA

[pennystocks]

I just filled my tank since getting the scangauge, i'll let you guys know exactly what each bar means.

[Dweeb]

^^^ each bar will be a bit different in different cars, and it also depends on how you drive. (how many miles you get per "bar")

[pennystocks]

I mean in gallons, so far the first one is 1.9 gallons

[suzu]

Its impossible to believe that the car could get >45 m/g. I am one of the first owners of 3dr manual lb in US. Don't drive it a lot. Has put ~1500miles and getting 38-39 m/g with roughly 50/50 city-expwy and freeway driving. I drive like a granny and baby the car to get the best mileage. Tell me if I am missing something but how could some of you guys getting nearly 45-5- m/g!!!!!

[Dylanby]

I believe the person getting those numbers is driving on the Great Plains highways. Not the same as freeway driving.

[pennystocks]

Just did a 30 mile run. Here it is:

30.9 miles drove
3400 max RPM
61 MPH avg
51.2 MPG avg

At about 65mph it drops to roughtly 45mpg then on the way back at 80 mph it doesnt' like goin above 35mpg

Keep in mind this is pure highway, no stops, not even slow downs (besides ipass toll booths to like 30mph)

I average normaly about 32-34 mpg but its 90% city and i cant really baby the thing sometimes. But w/ goin extremely easy on it i'v gotten 38-40 mpg city.

Its also easier w/ a MPG gauge too. Make sure you coast to a stop, alot, and even taking turns fast helps w/ MPG. Putting it in neutral helps too since for some reason when backing off the gas puts the PCM into open loop which causes it to slightly engine break and the car doesn't "en-lean" like the GM cars i'v owned.

Another factor is if you have a stick or an auto. If you have a stick your not going to shift 100% on time for the best MPG.

Auh long night, i'm crashin.

[NickNickNick]

1000km drive to Minot, ND from Regina, SK =

Just over 50L of fuel =

47mpg
5.1L/100km

Flat driving (in the prairies/plains) 110km/hr, very little city driving or slowing down.

(7.5 gallon fill in Minot, 20L left in Regina).

[Dweeb]

NickNickNick,

good for ya, but i still find these types of mileage hard to believe...

I can't get over 40MPG no matter what i do....

[fearturtle44]

As said before, people need to take the average after 3-4 full fill ups. Going one mile, adding gas, and saying "I am getting 200MPG" is pretty bad. Anything over 42 is wrong and anything under 30-32 is wrong.

Everybody should just realize that we are getting great MPG whether it be 35 or 40 mpg.

Kevin

[chuchu]

I was a little baffled when I saw that Toyota.ca listed the Yaris as getting something like 51mpg vs. the US Yaris's 40mpg until I realized the discrepency was between US mpg and imperial mpg.

It would be helpful if everyone who posts mpg specify whether it's US or imperial.

[Dweeb]

^^^ That would make too much sense, Plus we couldn’t argue if all of us agreed on something.

What fun would that be :thumbup:

Dweeb

[stuffy]

chuchu, i think that is what is happening here, people are posting imperial gallons and it looks like a totally inflated number

[swng]

Members used to encounter similar confusions in the earlier part of the "Fuel Economy" thread but now I think members who pay regular visits to that thread have already noticed the problem. Now, they often post their mpg numbers under both the Imperial and US systems. Some even also post their numbers under the metric system. Every now and then, members there post links to sites which calculate mpg numbers under practically all systems for free:smile:.

[ricko]

If this keeps up, we'll have members required to tell whether they were driving with or against the wind, when they post mileage figures. :bellyroll:

[pennystocks]

Going one mile, adding gas, and saying "I am getting 200MPG" is pretty bad.

I dont knwo if you missed it but i have a scan gauge.

http://scangauge.com for more info.

and the 51 MPG is US MPG, i live right above chicago as if thats enough to hint its US MPG

People say they are having trouble getting this milage, you will have to take a 500 mile trip w/o any stops in order to notice it on a tank fill up.

[swng]

Sorry ricko. Can't discuss at length here for fear of getting off topic though I like the point that you brought up two posts ago:wink:. Wind directions do count. However, the effects of different wind directions can be off set by taking long term averages with a big number of samples:smile:.
In other words, when one wants to get an idea of the fuel efficiency of the Yaris, one just need to read as many posts as possible by different members about the car's fuel economy in order to help oneself arrive at a reasonably accurate estimate:smile:.

[pennystocks]

Ok, this will clear up all the "i cant get that mpg, wtf"

Yaris US MPG:
34 city (short trips, lots of stops)
40 hwy (doing 55 mph or so, hitting a light every once in a while, maybe some traffic slow downs)
50 expwy (60 mph, no stops at all, this is my rating btw, not posted anywhere)

The yaris is rated at 39 mpg for the auto, it clearly states:

Aucutal milage will vary with options, driving conditoins, driving habits and vehicles conditons.
Results reported to the EPA indicate that the majority of vehicles with these estimates will achieve between:
28-40 city
33-45 hwy (at 80 mph i averaged 35 mpg, at 60 i averaged 51, sounds right within that range)

So 40 city and 45 hwy have been achieved.

[YotaYarisUSA]

That scan gauge looks pretty cool,is it hard to install? And can it harm the Yaris or void the warranty for the car? How accurate is it, and where can you buy one, besides their online site? Can you pick one up at ,say an Auto parts store,or something like that. I don't if I trust ordering online from their,website. How many ppl on here use Scan gauge?


Thanks,for your time

YotaYarisUSA

[pennystocks]

I know some online stores sell em but for the most part its online only. Easy install, jsut plugs into your obdii scan port. Its pretty much dead on, it said i used up 9.6 gallons, i could only squeze in 9.8 on my last fill up.

Seriously just having this has got me up 2-3 mpg.

[Blenjar]

God I cant wait till I get my Yaris late this year or early next year.

[YotaYarisUSA]

I think I'm going to order the scan gauge, check out this review http://hybridcars.about.com/od/ownership/fr/scangaugereview.htm plus what pennystocks says about it,this seems like a very useful tool and like the reviews say,it can say you money when and if that check engine light comes on :)


Have a great day!


YotaYarisUSA

[YotaYarisUSA]

Just ordered my scangauge, how long did it take to get yours? Their website says 2 day shipping,I hope I get mine soon :)



YotaYarisUSA

[pennystocks]

It says 2 day shipping but it also says 7 days to ship it :( Took em 2 weeks even for mine and it wasnt shipped on day 9 when i called em, then they shipped it. Auh man it felt like xmas when i got mine =D

Another thing thats kinda lame, you cant put any of the trip info into the gauge, like you can look at instant mpg, volts rpm throttle ect. all at once but you have to switch to the trip to get Avg. MPG, miles to empty ect. then swith back to the gauges. It'd be so nice to look at Avg. MPG and instand MPG at the same time.
I emailed em and they said they were looking at doing that in the future, also in august you can hook it up to a laptop, hopfully then upgrade it so it can do this

Also already had the check engine light come on once
p2118
Throttle Actuator Current Range/Performance Problem

Probaly nothing major, just cleared it.

[TRD_Yaris]

Couple Questions:

can you adjust the scangauge II for different tire profiles? For example, a large truck with BIG tires...

how sure are you guys about your vehicle weight? Don't you have to put in a decently accurate weight calculation for the scangauge to be accurate?

[robcrowell]

I'm getting about 38MPG with my Automatic sedan. I put a few hundred miles a week on my Yaris, mostly stop and start driving. I don't mean redlights or stop signs either. I work in advertising and visit around 20 clients each day. I drive and turn the car off, then start it up and go to the next place. I think 38 MPG is amazing for the type of driving I do!

[Chaad32]

I'm getting about 41mpg and I don't drive like an old lady...but I don't baby it either. And that is with the A/C on 2.

[asa805]

ok i dont get how people are getting these numbers. I seriously think somethign is wrong with myc ar and am wondering what if i should go in and have it looked at under teh warranty or complain to my dealer. Ive had my car almost 2 months and after 2 fillups im only getting 25mpg average. WTF??? Someone please tell me somethign must be wrong. I went to two different gas stations too ... i doubt both of them water down the gas.

IM so upset. :(

ps. i drive pretty slow, 65 tops but mostly 60ish on highways. I totally watch how i accelerate and slow/stop. I keep my foot off the brakes and coast when slowing down. Seriously im doing everythign right. Got my tire pressure checked and added some air. What gives ... really?

[Ryu]

The only thing i can think of is possibly you roll down the window while driving at highway speed, but I don't think you did.
Maybe the car is not broken in yet, it will get better fuel economy once broken in.

I consistantly get around 7.4 L/100km my first 8 fill u I guess, but now i got around 6.7L/100km now. Well may it is the break-in period, otherwise i can't think of any reason for you :confused:

Maybe you should TRY driving like you want to..and see if that changes things. I tried the same thing on a manual transmision truck not too long back : i ended up getting worse gas mileage when i was being "stingy" with the gas..Plus, the electronic throttle system takes some time to "learn and adjust" to the way you drive..

[Thirty-Nine]

Not to add fuel to the fire, but I avg. 32 mpg in my Scion xB, which is heavier and less aerodynamic. I'd follow TRD Yaris' advice, and if after a few tank you're still getting 25 mpg, I'd bring it in.

[stuffy]

asa805, you will see big improvements as your car breaks in, don't worry, my first few tanks went REALLY quick, i think the first was 27 mpg (u.s.),
i'm now around 35-40 mpg (depending on amount of city/hwy driving) with 10,000 km on the engine.

[fnkngrv]

I thought that Toyotas were sold already broken in before you buy? I have put 3200 miles on mine now and the worst tank was 37mpg....but mostly have been around the advertised 40. I would think about looking into a dealership to have them look at things for sure after taking TRD's advice.

[TRD_Yaris]

A couple questions for ya:

What type of fuel additives do they add in your area..in dallas area, they have been adding crappy stuff that's supposed to pollute less..but sucks.

Are you in high altitude?

Do you "rev-match" gears when you shift?

TRY FOLLOWING THIS SHIFT "schedule". I found this in the manual while rummaging.

**Page 128 2007 "Toyota Yaris Owner's Manual"
"Recommended Shifting Speeds - The transmission is fully synchronized and upshifting or downshifting is easy.

For the best compromise betweeen fuel economy and vehicle performance, you should upshift or downshift at the following speeds (sucks that it's not in RPMs..though it wouldn't matter for the liftback anyway :laugh: :mad: :mad: )


Low Altitude
gear mph
1 to 2 or 2 to 1 15
2 to 3 or 3 to 2 25
3 to 4 or 4 to 3 40
4 to 5 or 5 to 4 (45/40) <--dunno what this means..two values for manual trans?)





***Page 218- "2007 Toyota Yaris Owner's Manual"
Referred in Appendix as "Fuel Economy" :clap:

A LOT OF GOOD TIPS FOR PRIMO GAS MILEAGE INCLUDING PROPER TIRE PRESSURE, etc.etc.etc.etc.etc.etc.etc.


I'm a bit too busy to type out anymore of the manual, but i hope these help.
I actually shift from 1st to 2nd at about 20 (:biggrin: ) and from there it all seems pretty tame..but i don't have my scangauge runnin' max rpm so i dunno...I just kinda "feel" the way the car takes to the gears...

11.1 gallons.. i fill up within 10 miles of the first low gas level indicator and I can get 10.6 to 10.8 g in each fillup. I'm still putting together a 500 mile drive for delivery work this week...pure suburban at a fast pace. i'm keeping track of every gallon down to the .01 (gas receipts) and using the same fill-up station pump everytime... 500 miles on the trip 1 and beaucoups gas receipts = a darn good estimate of AVERAGE mileage and proof that the Scangauge II Datalogging of gas useage and mileage are indeed accurate :thumbup:

You also gotta consider that these cars have ELECTRONIC THROTTLE CONTROL..basically meaning that the computer accelerates the engine based off what you tell it..and what it decides is necessary. I don't know how the "learning logic" of it works..but it's supposed to "adjust" to your driving habits from datalogging how you've driven in the past. I had it in my Lexus, and it took some time to get use to..


I hope your mileage goes up.

[boxerboy]

Thanks for pointing out the info TRD. My wife has a RX300 with the vvt-i and I'm not sure at what rpm it gets the extra push, but you can feel it. How hard have you pushed your yaris and can you feel the vvt-i ? I only have 780 miles on mine so far.

[stuffy]

if the electronic throttle control adjusts to your driving habits, what happens when more than one person drives the car?

the only reason why i ask is because my wife drives way different than i do, she shifts at lower revs and doesn't downshift when braking

[Thirty-Nine]

VVT-i does not provide an extra push. VVTL-i does (the L stands for "lift," meaning the engine is increasing the valve lift for performance). VVTL-i is found on the 2ZZ-FE engine, which is found in the Celica GT-S, Corolla XRS and Matrix XRS.

yeah..but i thought it was a "2ZZ-GE"..but i'm probably wrong :laugh:

I can't really say much about pushing it, since i haven't actually taken my new liftback past 4500 rpm, but it does have a pretty good low end torque (which probably comes from the Variable Valve timing intelligence..which is pretty basic technology, in my opionion but does give high revving 4 cylinders low end torque..kinda the same result as VTEC for honda/acura)

Now that i mention it, i can't really remember if my Lexus had VVTiL right now..but that could be because i'm on my 4th Rum&Coke.. The difference there would be tough to compare anyway, since the lexus has a Supra 2JZ-GE which is WELL known for low end torque (INLINE 6, not V6)..so a top end coming on strong would be tough to feel :P

As far as multiple drivers of the car, i don't think the "learning computer" learns as much about the driver as much as Learn about the car itself and how it responds..in other words if the car *pings* a few times..maybe the computer learns that it needs to retard the timing a bit to compensate or enrich the fuel to smooth out something. but.. i'm probably wrong about this too. There is just too much stuff we are still simply ASSUMING..but as a community we will figure out these wily little rides.

[AlexK]

For the people who don't believe 50 mpg is possible in their Yaris, believe it.

My scangauge has been perfectly accurate, matching the measured tank mpg exactly. On the highway I got 48 mpg on a 230 mile road trip. I got 51 mpg on a 30 mile trip. Actually if you know how to drive for fuel economy, the best mpg will be city driving. The other day I got 59.5 mpg on my 8.8 mile trip to work. My friend has a Yaris sedan with AT and averaged 56.2 mpg on a 80 mile road trip but he was doing everything possible for mileage (including drafting semi's). So far he has bragging rights for best mpg on a long trip.

The best advice I can give to get better mpg in the Yaris is:
1) Drive like your brakes don't work. That means letting off the gas 1/2 mile before the red light, so you coast down to 20 mph before braking.
2) Upshift at low RPMs. I'm in 5th gear at 40 mph.
3) Don't engine brake. Coast in neutral instead. You would be amazed how far you can coast in neutral.

Great advice, I'd just add to do the speed limit or close to it and learn to relax while driving, we really don't need to be 3 feet from the car in front of us.
My last two tanks have been 46mpg(us) or 5.1l/100km by using the above techniques and tires inflated to 40psi cold.
I just changed to AMS synthetic oil... we'll see if that helps a bit more.

[xtrred]

I just got 480 miles to my last tank, and I think I can go further. The CEL hasn't come on at low fuel level yet, so I have more miles left at fill up I think.

I' don't always baby it either. It cracks me up to try and here the VVT-i, and I think I can sometimes! but yeayh, shooting for +500 miles a tank on 87 octane.

awesome advise.
i have just got into the habit of coasting, to the point now that it seems natural to do so. my mpg's keep going up every tank as i get more effeciant.

soon, scangauge to come :)

[fantabulousbaby]

Um, can yall pls explain to me how ur calculating miles per gallon? The capacity is supposed to be 11.2 gallons, but you never use 'all of it' until you fill ur next tank. I set my tripometer to zero and filled up till the thing clicked, it said 10.83 gallons on receipt, and there are 8 gas bars. Do you divide it? Also I can't accurately tell how many miles to the tank I get cuz once the u get to the last bar it starts blinking, and according to the manual it says the faster it blinks the lower you are on gas.. well how r u supposed to know what's considered fast blinking? I'm just curious how you guys r saying 'I get so and so to the gallon'. I guess I could estimate.. :iono:

Also I can't accurately tell how many miles to the tank I get cuz once the u get to the last bar it starts blinking, and according to the manual it says the faster it blinks the lower you are on gas.. well how r u supposed to know what's considered fast blinking? I'm just curious how you guys r saying 'I get so and so to the gallon'. I guess I could estimate.. :iono:

I would do this: Write down the current mileage on the receipt you got, then after "the thing clicks" at your NEXT fill-up, note the mileage AND the number of gallons just went in the tank. Then, subtract the last mileage from this mileage, and divide the result by the gallons just went in the tank. That means the mileage you drove from the last fill-up divided by the gallons your Yaris drank from last fill-up.

I calculate my mpg in two ways.

The first way is by the tank. Reset your trip meter when you fill up your tank. When it's time to fill up again, record how many gallons you put in to fill it (that's how many you used to drive those miles you have on the trip meter). Divide miles driven by gallons used, for example my last tank was 449 miles / 10.1 gallons = 44.5 mpg. You don't need to drain the tank to do this. If you don't fill up to exactly the same level every time it doesn't really matter, because if you record the mpg of every tank, the average result will be correct.

The second way is a lot more fun. A scangauge automatically shows gas mileage for the current trip. It does a lot of other stuff too. Check it out here: http://www.scangauge.com/. Using the scangauge you can learn to drive super-efficiently and get incredible gas mileage.

So I'm guessing the scanguauge will work in a 2007 yaris liftback. I don't understand how it connects to the computer in the car. WHere is the obdII port

The port is typically under the dash board in the vacinity of the steering colum, hood popper. That was true of my Subaru ( I was always checking my CEL lights) so I'm ASSUMING it's in the same general area :p

The OBDII port is affixed to the bottom of the dash, pointing down, on the left hand side on North American cars.
I'ts just below the swing out storage bin by the drivers left knee.
I just installed my Scangauge last night... very cool gadget.

Thanks for that info.. I'm guessing its the white plug in port just under the fuse box. Is that what you mean. It looks like a rectangular plug port.

Yep!:thumbsup:

Cool, just ordered a scangaugeII. Didn't realize it would be that easy to plug in. What a great little gadget.
